Planning Your Trip
When to Visit Thailand
Thailand is open all year round but the best time to visit depends on the region.
If you’re heading to northern Thailand the cool season from November to February is perfect for sightseeing and outdoor activities.
If southern Thailand is on your itinerary the hot season from March to May is the best time to hit the beaches and islands.
But steer clear of the rainy season from June to October especially in the south as heavy rain can ruin your travel plans.
For island hopping the west coast is best visited from December to April and the east coast from May to October.
Getting to Thailand
Thailand is well connected to the world with several international airports, the biggest and busiest being Suvarnabhumi Airport (BKK) in Bangkok. You can fly into Bangkok from most major cities around the world so it’s a great starting point for your adventure. From Bangkok, you can fly, by bus or train to other parts of the country. If you’re coming from neighboring countries you can enter Thailand by land or sea which gives you more flexibility in your travel plans.
